Wi-Fi was missing on a laptop. What to do if Wi-Fi is missing on a laptop with Windows

The Internet breaks through a Wi-Fi router (why Wi-Fi network falls off or disappears)

Hello!

Today in this note I want to touch on the problem of unstable Wi-Fi operation: when the Internet breaks off at certain intervals of time. Of course, with this problem you can forget about the comfortable viewing of online video, network games, etc.D.

The elimination of such work Wi-Fi (in my opinion) is more difficult than if the network simply had not worked. When there is no clear reason, you have to check different options, diagnose, etc.

In general, be that as it may, if you are faced with a constant cliff of communication on Wi-Fi, then the first thing that I recommend:

• Reload the computer (laptop) and router;
• Connect add. device (second laptop, phone) to the same Wi-Fi network and see if the connection on both devices will be lost, or only on one;
• check with the Internet provider whether they are all right with the channel, is there any preventive work on this day.

Why breaks and disappears Wi-Fi

High load on the router

The most common reason for the periodic loss of the Internet via Wi-Fi (and the network itself) is the reboot of the router. its transformation to the Internet (just at this moment for 5-15 seconds. The connection disappears).

Retrilling a router can occur for various reasons, but most often due to a high load (for example, if you actively download torrent files). Typically, this happens with inexpensive budget models of devices that simply cannot cope with the load and go to the rebell.

• open the settings of the router (how to do this);
• Further, in the wireless network settings, you should try to change the security mode with WPA2-PSK to something less demanding, for example, on WEP or WPA (or for a while without a password at all). This will reduce the load on the router and quickly identify the cause (important! This is done only for the purpose of diagnosis, do not leave the network without protection for good!);

Actually, if, after the procedures done, Wi-Fi stopped falling, then you can further:

• or leave everything as it is and use a router with speed restrictions;
• either purchase a router more powerful, which can hold a high load.

A coincident radio channel

If you live in an apartment building, then dozens of others saw when searching and connecting and connecting to your Wi-Fi network. Each such network works at its own frequency (radio channel). Usually, the Router radio channel puts automatically, itself.

However, if several routers are close to one radio channel near: the connection can periodically break off, the speed of the network will be low.

To check which radio channels are busy near you. You can recommend one small utility Insider. As can be seen from the screen below, channels 2, 7, 5, 1 are free.

Note: Channel from 1 to 13 are used in.

Wi-Fi channels/INSSIDER PROCESS (Link to the utility: https: // Inssider.ru.Uptodown.COM/Windows)

Actually, then you can try to put a free radio channel in the router’s settings and look at the difference. Will Wi-Fi start working steadily.

Router firmware

The firmware is a special micro.program, thanks to which the router “knows” what he and when to do. In some cases, there may be errors in the firmware, because of which a router may not behave stably, for example, reboot, tear communication, and slow down.

Of course, in most models of routers you can simply change the firmware (if it exists for it). As a rule, it is enough to open the router settings, go to the device control tab, and click on the micro.program update button.

Note: Rotter flashing can lead to a malfunction of the device (therefore it is important to choose a firmware for exactly your router model). In addition, after the firmware, you will be denied warranty service.

I note that the micro.program (firmware) is (most often) the most ordinary file with the extension.Bin, for example, “US_AC5V1.0rtl_v15.03.06.32_multi_tru01.Bin “.

How to change the firmware of the Wi-Fi router (update of the microprocrogram)-see. Step.by.step primmer

You can download a new version of the firmware from the official site of the manufacturer of your device.

Wi-Fi is there, but there is no Internet: what to do

In general, according to statistics, it should be noted that most of the problems with the inaccessibility of the Internet (when connecting to the Wi-Fi network) is associated with the settings of the router. But if you have other devices connected to the same Wi-Fi network can go to the Internet [like the author of the question], then you should start with checking Windows settings.

Approx. : In addition to those cases when a restriction on the number of connected devices can be placed in the router settings (or there is a “white” list for specific MAC addresses (what is the MAC address)).

In this case, if the Windows setup did not give results. Check the settings of the router (about them just below in the article).

Perhaps this is the first thing to start with. The fact is that often the previous settings remain in the settings of the network connection (which, for example, could be set in the store). And because of this, when you connect with a Wi-Fi network, the Internet does not work.

To get started, open the network connection tab (for this: click the combination of Winr. and in the “Perform” window that appears, enter the NCPA command.CPL).

NCPA.CPL. viewing all network connections

Next, open the properties of the wireless network (in English. It can be called “wireless”).

After find the line “IP version 4 (TCP/IPV4)” and open its properties (number-1 on the screenshot below).

Next, install options for obtaining IP addresses and DNS server automatically (these settings are suitable for most routers!).

Obtaining automatically IP, DNS / clickable

Save the settings and double.check the network.

The second thing I would like to pay attention to is antiviruses. Often, trying to protect your work on the Internet. They block access to many sites (or do not allow the browser to work at all until you allow this action manually.

For example, this was how Norton Antivirus and Panda did when setting max. level of protection).

Therefore, during the setting of the network, I would recommend disconnecting the operation of antivirus and firewall.

If you have Windows 10 (11), then in its arsenal there is a good network diagnostics. Often, it helps if you do not eliminate the problem, so at least indicates the reason for its occurrence.

To start diagnostics: just click on the network icon in the triad, with the right mouse button, in the menu that appears, select the option “Diagnostics of problems”. There is and others. Launch method.

Next, act according to the advice of the “Master”.

By the way, you can also open Windows parameters, tab “Update and safety/troubleshooting”. In the list find a “network adapter” and start a means of eliminating problems (see. screenshot below).

Elimination of networks of network adapter / Windows 10

Try using DNS servers that are different from your provider

It may become so that on your other devices (on which there is the Internet), excellent DNS servers from your provider are set in the settings.

As a result, they work, and specifically your new device. No. By the way, I note that the DNS servers of the provider are often inferior, for example, DNS servers Yandex or Google. Therefore, I also recommend trying to change them.

To do this, open network connections, then the properties of the adapter (in the previous step, it is described in detail how to do this) and try to use DNS 8.eight.eight.8 and 8.eight.four.4 (as in the example below).

To help!

You can find out more about DNS servers (and how it can affect the work of the same browser)

Properties IPV4. Get IP address automatically, we use the DNS server from Google

In addition!

I would also recommend that you familiarize yourself with another article, which indicates a number of reasons for the Wi-Fi network without access to the Internet

The problem is on the side of the router (if there is no Internet on all devices connected to the Wi-Fi network)

If there is no Internet on any of the device connected to Wi-Fi, then you can almost certainly blame the router (at least first of all check its work). In general, malfunctions in the work of the router, unfortunately, are not so rare.

If you used to work as a normal mode (normal), then for starters, try Reload the router. Often, a router with strong load can “submit” or restart, and create a new connection “forgets”.

Whether the Internet access parameters have lost (and is the router configured at all)

In some cases, settings for access to the Internet (usually the WAN section in routers) can be lost. By the way, if you have a new router and you only connected it for the first time, then you are not given at all, and the absence of the Internet in this case is not an amazing thing.

To check the settings, you need to go to the router web-integer, as a rule, it is enough to enter into the address bar of the browser IP 192.168.one.1 or 192.168.0.1 (link to the instructions below). Then open the Internet settings section (WAN).

2) How to set up a new Wi-Fi Roter yourself.

Due to the abundance of various brands of routers and their firmware, it is hardly possible to give 100%instructions. For example, in Tenda routers, this section is called “Internet settings” (see. screenshot below).

You need to introduce the parameters of access to the Internet that the provider provided to you when concluding a contract for the provision of communication services.

Usually, if it is a pppoE connection (one of the most popular login and password for access to the Internet. Sometimes you need to specify certain IP addresses, DNS, etc.

PPPOE Settings Connect / Tenda router

As another example-the TP-Link router settings window (section “Network/Wan”). In principle, all fields are similar, for filling them, data from the contract with the provider will also be needed.

In addition!

I also recommend one previous article on how to set up a router (Tenda FH456 was taken as a basis): Create a connection to the Internet and Wi-Fi

Are there any restrictions on the number of connected devices (is there a block by MAC address)

In some routers, you can set special security settings: for example, allowed to connect only a certain number of devices, limit the devices by MAC address, etc.

Or in general, as in the bandwidth strip settings (Tenda router). you can disable access to the Internet for any of the devices!

I recommend checking these settings and making adjustments.

Passing strips / Tenda router / clickable

By the way, I suppose that it is far from always so easy to “pass” all the safety settings of the router (especially if you do this for the first time).

In some cases, it is much faster to reset the router settings into default (by default) and then manually set the parameters again. To reset the router settings, they have (most often) a small barely noticeable “Reset” button (you need to press it with a pencil).

Roter/router settings button

Check the balance of the provider. Are there any problems on his side

If everything is in order with the settings. also pay attention to the work of the provider. Some providers have those. Work is not so rare (especially if you have old equipment in the area, or other users are actively connected in your house). Try to clarify in those. support. Are there any ones. work, and check your personal account. Is there any means there.

The advice may seem too banal. But I had a case: I paid for communication services at once for six months in advance.

A month later, the Internet provider raised tariffs for its services, and my prepayment was enough only for 3 months. (After the Internet is disconnected, it was somewhat surprised by such a reason. ).

Well, another is not such a rare reason-this is a break in the Internet cable. For example, in the apartment it is often gnawed by pets, in the entrance. “barbarians”. Also, the cable is also often interrupted when rearranging furniture, heavy items.

This is how it happens too: the cable was barbarously torn in the entrance of the house.

Wi-Fi recovery methods on a laptop

There are several ways to restore Wi-Fi at the moment when the laptop does not see the network.

Disconnecting the mode on the aircraft

First, check if your device has a mechanical key or mode switch, try to turn it on. There are situations when people accidentally press the key, and at the same time remain confident that they did not do this. The function of the aircraft mode appeared in the tenth version of Windows, and if you accidentally turn it on, your computer simply will not see a router. The icon of this mode can be found in the field of notifications, to turn on and off this mode, you just need to click on this key.

Disconnecting energy conservation

In some situations, the computer does not recognize Wi-Fi due to the fact that it includes energy conservation mode. Be sure to check this item in the settings.

Disconnecting fast loading

If the laptop does not see the Wi-Fi network, try turning off the quick download. Of course, this function is built into your device, however, it is not convenient for all users. The work of quick loading should not cause damage to the computer, but in some cases it is better to turn it off. When turning on from quick start, different problems can occur, including the computer may stop seeing Wi-Fi.

REVELING ROURTER

If you look at the rear panel of the router, then you can find a button for its reboot. You need to press it, wait a few seconds and release. During the reboot, the ruter cache will be cleaned and new settings will be obtained from the provider. Sometimes a computer does not see a wireless network due to a malfunction failure.

Checking the adapter

Often the computer does not see Wi-Fi because this module is simply disabled in the system itself.

In order to enable this module again, you need to go to the network control center, and then click on the adapter change button. At a wireless connection, click the power button, after you activate this module, the device will again begin to look for available networks.

Checking the drivers

In some situations, the laptop does not see the router after you update the driver of the wireless module. In some models, the wireless module is attached to the network card, however, most often this part is performed as a separate board. In order to solve this problem, you need to go to the device manager and go to the section of network adapters. Sometimes the module is placed in other devices. Then you need to click on the module with the right mouse button and select the driver’s update item. Then you just have to wait until the drivers are updated.

It is best to download drivers only from the official sites of the manufacturer.

Checking the router settings

In some cases, the computer does not see Wi-Fi because the settings have lost. The settings, in turn, are lost due to the effects of harmful programs or when the voltage changes. The settings of your device change, as a result, access to the network disappears. In order to solve this problem, you will have to configure the router again according to your provider’s instructions. If the reason is that malicious software is located on your computer, before starting work it must be removed using antivirus programs.

Network reset

If your laptop does not see the network, you can discharge it. Separately, this function began to appear in Windows 10, in order to use this function, you need to go into the parameters of the system, and then go to the Internet section. Then all the contents need to be scrollful to the bottom, there will be a discharge point. As a result, a new window will open in order to confirm your actions, you need to click on the “Reset now” button.

In order to reset network settings on earlier versions of Windows, you need to go to the command line. Open the command line and enter the Netsh Winsock Reset command in the window that appears and click on the Enter button. Then you need to wait for the moment when you receive a notification of the successful execution of this operation, after all this you need to restart your laptop. In addition, if your laptop no longer sees Wi-Fi, you can clean the cache, this is also done through the command line. In the event that you conducted the procedure correctly, you will receive a message about the successful completion of the procedure.

In some cases, to establish a wireless adapter, you have to update the protocols.

Are there any drivers? Checking and updating

When installing Windows driver for Wi-Fi, they are far from always installed (of course, Windows 10 supports a lot of equipment, but not everything, all the more so to say about Windows 7. ).

To check if you have drivers for the adapter Wi-Fi, go to the device dispatcher and open the “Network Adapters” and “Other devices” tab.

On the screen below it is shown that there are no “Wireless Network Adapter” in network adapters in network adapters. or “wireless adapter. “. And in the “Other devices” tab there is a device with an exclamation mark. There is a problem-the absence of a Wi-Fi adapter driver.

Network settings, discharge on auto-disclosure

Often there are problems with wireless connection due to the fact that the connection settings in the properties of the network adapter were changed.

To check it and fix it, first open the network connection tab:

• Press the Winr buttons;
• Enter NCPA.CPL and click Enter (as on the screen below);
• You can also open this tab through the Windows control panel.

NCPA.CPL. viewing all network connections

In network connections, open the properties of your wireless adapter (see. screenshot below).

Next, find the line “IP version 4 (TCP/IPV4)”. Highlight it and go into its properties (arrows 1 and 2 on the left on the screenshot below).

Then save the settings and try to connect to Wi-Fi again.

Change Wi-Fi parameters

We enter the “Networks Management Center”, choosing our connection. We go to the “Properties of the Wireless Network” set the “Connect, even if the network”.

If any of the actions taken helped and the Internet, as before, fails, then in the network of the network of the Safety tab you can click the “Additional Properties” key and install the flag on the parameter include compatibility with FIPS. After rebooting, the problems should disappear.

Features of Windows 7

In the seventh operating system, it happens that “Windows” itself does not show an affordable connection. This may be the result of unlicensed software. Sometimes such cases occur due to excessive amounts of unused files, which leads to overloading equipment and systems.

Reasons why the laptop cannot identify one or all access points, a lot. To eliminate, you can try the above methods. And if nothing happens, then there is only one way out. contact the service center.

Problems with a router

If the laptop reveals available Wi-Fi networks without problems, but when connecting to the right one, it gives out an error, most likely the router is faulty or its settings are set incorrectly. You can diagnose the problem by connecting the cable and driving into the address bar of the browser “192.168.0.0 “.

• In the dialog box that opens, it is necessary to specify “admin”.
• Then you need to check the distribution of the Wi-Fi signal.
• Next, you need to make sure that the address is not included in the “black list” of MAC filters.

After performing the algorithm described above, it remains to check whether the possibility of simultaneously connecting two or more devices to the router is activated. If you cannot connect the laptop to the router even with the help of a cable, it is worth pressing the Reset key and repeat the attempt in 20 seconds.

Important! If these recommendations have not led to a positive result, you need to call the provider and learn about the availability of feedback from the router. In the case of a negative answer, the probability of its failure is likely.

Obstacles for the signal

For stable work of a home wireless network, a specific channel is used. However, neighboring networks are interfering that prevent the normal signal of the signal. The cause of interference may be household electrical appliances, which, combined with walls, partitions, cabinets and other furniture items, worsen the quality of communication. What to do to solve this problem? It is worth reducing the distance between the router and the laptop or use the signal amplifiers.

Often the solution of the question “Why is the Wi-Fi signal is unstable?»Hides in the remoteness of the router from the laptop. You can check the signal level by connecting a mobile phone to a network within a radius of not more than 1.5 meters from a distributing device. If the ability to reduce the distance between the laptop and the router is absent, it is worth additionally involved in the external directional antenna, signal amplifier or special retranster.

If the problem arose after reinstalling Windows

Non-avoctions of connection may appear due to the following circumstances:

• After updating Windows.
• Due to the reinstalling of the drivers.
• Due to the change of settings.
• After repair or mandatory cleaning the gadget.

The Wi-Fi adapter from the device manager

In the case of the disappearance of the adapter icon from the devices dispatcher in the control panel, only a Bluetooth connection and a local network will be active. To restore the “wireless network”, it is necessary to open the “Network Adapters” tab. In the window that opened, most likely, some unknown device or name with a yellow exclamation mark will be displayed. Most often, this is the adapter necessary for further work, which simply flew due to problems with the drivers. You can get out of this hardware problem only by reinstalling the drivers or using the wire connection of the adapter via USB.

The absence of a router in the device panel or its inactive state can lead to the absence of the Internet

In the event that there are no devices that relate to a wireless connection in the window that opens, even absolutely unknown, then the only way out is a repair workshop.

Installation of drivers

The variety of “walking” in the network of drivers is far from always suitable for a specific model. The program can be just outdated. To obtain the necessary information, it is recommended to contact the adapter manufacturer directly and only then download it, and even more so install it on your laptop.

All work on installing drivers can be done independently. The sequence of work is prescribed by the simplest and most understandable language on the manufacturer’s website and is almost automatically.

Driving program for the required driver

Energy saving settings

Windows operating system is endowed with an internal opportunity to analyze the use of certain components. If for a long time they are not used for a long time, then the program automatically turns them off at the system level. The developers explain this function by saving the battery, which is the only source of laptop power. You can disable it from the control panel. In this section you need to select the “Power Power” item and open the subparagraph “Setting Scheme”.

After you should open the “Change additional parameters” link and already inside the system open the “Adapter Parameters” and translate the runner into maximum performance. Be sure to click at the end of the path. If you do not fulfill the last point, then the problem will be repeated, as before.

Route settings

In some cases, the problem can be solved by a simple setting of the router. Unstable work is sometimes possible to resume through rebooting. In some cases, it may be necessary to perform several disconnects at once, including.

If these actions did not help, then you need to pay attention to the updates, which must be performed. These actions will lead to a collapse of all systemic errors that have arisen in the process. If these actions do not help, it is necessary to carry out a full reset of all the settings of the router.

Important! It is recommended to move to the last point only when the user is familiar with all the data and parameters of the equipment used. If not, only the provider will help.

The setting of the router should be performed sequentially

The Internet disappears through a router every 5 minutes

The Internet connection can be unstable when the incoming signal is very weak. In this case, the connection will be constantly interrupted and, accordingly, the router from the laptop will turn off.

You can correct the situation with the help of an endangered antenna or by turning to the provider. For example, a corresponding icon will appear on the screen of a mobile router, which will notify the user about a weak signal. Having called the hotline on the phone, it is necessary to outline the problem in detail.

Important! All information about the level of admission at a particular point can be found on the official website of the provider or find out from specialists by phone.

Settings

Sometimes the problem is deeper, in the settings of computer technology. They can be initially done incorrectly or a violation occurred, after a system failure. The solution must be sought in the settings of the operating system or BIOS.

How to restore the Internet on a laptop if the adapter is physically disconnected in BIOS:

• First restart the computer, then hold the corresponding key to enter the BIOS menu during loading. On different models of laptopes, these are different buttons. For example, you need to hold F2 on ASUS, but on HP. “del”.
• You need to go to the Configuration tab, select the wireless line and make sure that the module is activated. If it is turned off, then you need to turn on.
• Next, press the F10 button on the keyboard to save the settings and restart the computer again.

If everything is in order with the laptop, then go to the router settings. It is important to understand whether all the lines are spelled out or there is no information.

The settings prescribe information indicated on the rear cover of the router. After the entered data was saved, reloading of equipment and re.connection to the network are required. Sometimes the router does not manage to connect to Internet or to the selected IP address. Then you will have to set up the network by hand.

• connect an Internet cable to a computer;
• Introduce the line “192.168.0.0 “and confirm the actions of the key. Enter;
• Check the settings, and then connect to Wi-Fi.

It will not be possible to carry out the procedure if the router does not have the opportunity to work at once on several devices. Sometimes the absence of a connection may be due to the fact that the address to which the connection is made is blacklisted with the MAC filter.

Extreme option, reset the settings of the router to factory. To do this, press the Reset key, which is on the side of the device, and hold for a few seconds.

Reset key

Reinstalling the Wi-Fi driver

When it was established that the Wi-Fi network disappeared from the list of networks because there are no drivers, you need to reinstall them. This requires to find a disk that is provided in a box with a laptop. In modern models, the necessary files are stored in the system disk. If the drivers are not found, they must be downloaded.

• Go to the official website of the developer;
• Select the section “Drivers”, where you need to find a laptop model, version and discharge;
• Carry out the file on the laptop, guided by the technical characteristics of the device;
• Install the drivers.

When the installation ends, the system will automatically connect the drivers, but if this does not happen, you need to go to the “Device Manager” section, find and press the “update the driver” key.

Update drivers

Wi-Fi may disappear for a number of reasons. Three main solutions will help to fix the situation: the reloading of the system or the search for the cause via the “Network Connections” or “Device Manager” tab. Just go into the tab and press the “Connect” key. If this did not help and the Internet continues to disappear, it is possible that the problem with the drivers. Then they are required to reinstate them or is recommended to reset the router settings to factory.
